Solar Companies in the Philippines
Solar has gone mainstream across the Philippines, and with it the number of companies offering it — from established engineering firms to one-person resellers. The hardware is only part of the job; the difference between a system that quietly pays off for 25 years and one that becomes a headache is the company behind it. Here's how to tell them apart before you commit.
What a good solar company actually does
Supplying panels is the easy part. A proper solar provider handles the whole lifecycle — engineering, procurement and construction (EPC) — and stands behind it afterwards. When you compare companies, compare across all of it, not just the equipment on the quote.
Site assessment
A real look at your roof, your electrical setup, and — most importantly — your actual consumption from your bills, before any system size is proposed.
Engineering & design
A system designed to the Philippine Electrical Code and to your roof and load, not a size pulled off a price list.
Procurement
Sourcing the right, genuine equipment for the design — inverters and panels matched to the job, with headroom to expand later where it makes sense.
Installation & commissioning
A safe, code-compliant install, tested and demonstrated to you so you know it works before the team leaves.
Documentation & handover
As-built drawings, equipment serial numbers, warranty certificates, monitoring access and operating instructions — the paperwork that protects you for years.
After-sales support
Someone who answers when you call months later. Ongoing maintenance and a real point of contact, not a number that stops working after payment.
How to evaluate a solar company
Use these as a checklist. A company worth hiring will be able to answer all of them plainly.
A real, registered business
Look for a registered business you can verify — not just a Facebook page. It matters when you need warranty support two years from now.
Straight about scope
Permits, inspections and net-metering applications are often the customer's responsibility. A good company tells you clearly what it does and doesn't handle, in writing, rather than implying everything is covered.
Honest about savings
Solar can substantially reduce a bill, but no legitimate company promises to eliminate it — your usage, when you use power, and your roof all decide the outcome. Be wary of anyone guaranteeing a zero bill.
Proper engineering
The design should follow the Philippine Electrical Code and suit your roof and load. Ask to see the system design, not just a total.
Clear documentation
Insist on a defined handover: drawings, serial numbers, warranty certificates and monitoring access. If "done" isn't defined, it can't be enforced.
Genuine after-sales
Ask what support you get after installation and for how long. The cheapest quote is expensive if no one picks up when something needs attention.
Questions to ask before you sign
- → Can you show me a registered business and a way to reach you long after installation?
- → What exactly is in your scope — and what is mine? (permits, inspection, net metering)
- → How did you arrive at this system size — from my roof and my bills, or from a price list?
- → What documentation do I receive at handover, and when is the project considered complete?
- → What after-sales support and maintenance is included, and for how long?
- → Is the inverter sized with headroom so I can add panels later if my usage grows?
Arranging solar for family in the Philippines from abroad
Many of our enquiries come from Filipinos working overseas who want to put solar on a family home back home. It's a smart gift — it cuts a bill their family pays every month for decades — but from abroad the hard part is knowing a company is legitimate and not a fly-by-night. Here's how to make sure you're dealing with a real one, wherever you are:
Verify the business, not just the page
Ask for a registered business you can check — not only a Facebook page or a mobile number. A real company is happy to prove it exists.
Insist on a written scope and quote
Everything in writing: the system design, what's included, the payment terms, and who handles permits and net metering. Never send money on a verbal promise.
Use a family member on the ground
Have someone on-site for the assessment and the installation, and keep the handover documents — drawings, serial numbers, warranty certificates. It protects your investment for years.
Watch it from anywhere
A proper installation comes with monitoring access, so you can see the system working from wherever you are — real reassurance that what you paid for is actually running.
Solar Switch works this way with overseas clients regularly — a registered business, a written scope, a documented handover, and monitoring access so you can check in from abroad. We'll coordinate with whoever is on-site and keep you in the loop at each step.
Where Solar Switch fits
Solar Switch is a registered Philippine business based in Imus, Cavite, providing full-lifecycle (EPC) solar — engineering, procurement and construction — for homes and businesses, and servicing systems across the country. Every installation includes a defined handover package and five years of after-sales maintenance, and we're straight with you about what is and isn't in our scope. We don't promise a zero bill or quote a price before we've understood your roof and your consumption — because an honest number is worth more than an impressive one.
